WILLIAM HENDERSON, OF NEW YORK, N. Y.

WINDOW-CAME.

Application filed July 23, 1909.

To all whom it may concern:

lie it known that l, \VILLIAM llnxn -zusow, a subject of the King o'l (iroal. lillllllll, residing at New York, county and State oli New York, have invented certain new and useful lmprorcnmnts in Window-tlames, of which the following is a spceilicallon.

My invention relates to im n'ovemenls in metallic glazing bars employed in loaded glass work for ornamental or stanu'd glass windows.

It relates further to window ran its or bars built up with an internal still'ennig frame whose exposed surface is covered wholly or in part with a layer of metallic lead or lead simulating material.

It relates particularly to the class of met'allic window bars of the hind set forth in my U. S. Patent No. at 5:13, of May ltlth, 1893, in which is dc.

ibed a hard sheetmetal bar having marginal heads, with a seat. or recess between said heads to receive and hold the glass panes.

The object of my invention is to produce an ornamental and artistic window came, which, while preserving all the beautiful. effects of the antique leaded glass, shall have suiiicient strength to permit of the use of panes of glass of any desired size. and weight, and to resist. distortion from wind pressure and gravity.

A further object of my invention is to furnish a leaded glass came of reastmable size and weight, thereby assuring the fine lines necessary for windows bullt up of small glass panes. In other words, I produce a came strong enough to use wlth large heavy panes, and yet so delicately l ned as to be capable of employment in windows built up of small panes, without the leaded cames being too large for the glass portion, thereby marring the desired effect from the artistic standpoint.

Another and important object of my invention is to produce a composite lead or lead imitating came, which shall be durable, easily, rapidly and economically manufactured, and capable of being installed without the necessity for such skilled labor as has hitherto been the case in high grade glass glazing.

My invention is designed to restore to architecture the antique leaded glass windows, which on account of their artistic effect are so much admired, but which having been hitherto fashioned slowly and labo- Specification of Letters Patent.

riously by hand, are seldom seen in modern slrurlurt-s, on account ol the time and expense involved.

The ancient method of making leaded glass ranu's was to cast the lead into an H-shapc, and then to reduce the rusting to the required size and weight by means of hand tools. 'lhis manipulation gave the great. (harm to leaded glass, and the cll'cct was heightened by a certain artistic irregularity of outline that the ancient lead gluzier inipressed upon the values, which artistic loaded el'lcvt l easily and cheaply reproduce. The old method was slow and costly, the cames too weak. and the linished article too weight and bulky for modern use. To meet modern requirements as to weight. and size, the lead mill and the l'iydraulic press were introduced, but atv the expense of the effect so desirable and at a sacrifice of durability and strength.

13y my invention the old leaded glass effeet is restored, strength and. durability are added, the cost very materially reduced, and the. weight adapted to modern requirements.

In the ata'zompanying drawings :Figure 1 shows portions of a. window built up with my improved eames, the upper part showing irregular, the lower, practically straight outlines; Fig. 2 is a perspective View, with end section of a straight edged came provided with the leaden coating, and Fig. 3 is a similar view of a like came having artistically irregular outlines.

Referring to the drawings :1 is the glass pane inclosed by the came 2, bounded by irregular lines 3, or by practically straight lines 4. To further increase the artistic antique effect, the surface of the composite came 2 is roughened by heat or chemical action to produce the irregular surface 5, and lumps of solder 6, or the like, are added at the junctions of the cames.

To carry out my invention, I form a sheet-metal H-shaped came, 7, preferably (for reasons of strength and economy in manipulation) of one piece substantially as set forth in my U. S. Patent No. 497,543, of May 16, 1893. To the stiff sheet-metal came thus provided, I apply by dipping, heat, brazing, or chemical action, an external coating 8, of lead or lead imitating material, to the outlines of Which I can give irregular or substantially straight form, and the surface of which may be artistically roughened as before set forth.

I do not desire to limit myself to the use of a one-piece came, the essential feature being the H-shape, the light, strong sheetmetal foundation and the lead or lead imitating layer covering the entire surface of the came, or only the portion exposed to view. The external coating may be lead, tin, zinc, or alloys thereof, or any lead simulating metal.

I do not herein desire to claim a metal came having an irregular outline, that forming the subject matter of an application filed simultaneously herewith, Serial No. 509,179.

Having thus fully described and illustrated my invention, What I claim, is

1. A sheet-metal came Whose exposed sur face is covered with lead or lead imitating metal.

2. A sheet-metal came having an external layer of metallic lead artificially roughened, as and for the purpose set forth.

3. A came for leaded glass windows having an H-shaped internal structure to Which is externally ap plie l a layer of lgad artiiicially I'OUgEIGIIGLl tU'IIl ivhose ii'regularities are increased at the junctions of the eames by added amounts of deposited metal.

4. A sheet-metal H-shaped came Whose exposed surface is covered With lead or lead simulating metal.

5. An H-shaped, one-piece sheet-metal came Whose external surface is covered with. a layer of lead or lead simulating metal.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses, this 22d day of July 1909.
